Abstract: A process for purifying a hydrocarbon is characterised by removing mercury by contact at over 90C with a solid sorbent comprising sulfided metal. The active material of the sorbent is based on at least one transition metal from groups IB, IIIA to VIIA and VIII of the Periodic Table quoted in the European Patents Handbook Part I Chapter 6.16.4 (1983). The process may be operated operated in conjunction with one or more of:<BR> ```arsenic removal by contacting with lead oxide 20-30% (as PbO) on alumina.;<BR> ```purification at 10-50C by contact with copper oxide/zinc oxide or with activated<BR> ```carbon, which may contain sulfur; and<BR> ```drying to a water dew-point under 4C. In an important application the hydrocarbon feedstock is raw or partly purified natural gas and the process is operated in combination with the stages of pre-cut, debutanisation and condensate splitting.

Title: Inflatable plastics cushion releasably held in a rigid frame
Inventor: MORRIS BENEDICT GEORGE
IPC: E04H15/64
Filed: 2002-04-02
Abstract: A building component comprising an inflatable cushion (51) including two or more sheets of plastics foil, preferably ETFE, supported by a relatively rigid frame (52) and further includes a mechanism for releasing the cushion from the frame.

Title: Method for tuning print engine operating parameters
Inventor: CHADEZ CLAYTON E
IPC: G06K15/00
Filed: 1999-09-30
Abstract: A printer (22) performs both the processing and printing tasks efficiently using controller firmware (26) with a single data path (i.e., one ASIC). The printer has a periodic print cycle in which data for one page or plane (if multi-colored) is printed during each cycle. The print cycle is typically longer than the time needed to print one page or plane. Thus, the print cycle can be segmented into a "printing phase" in which the printing mechanism prints data, and a "non-printing" phase in which the printing mechanism does not print data. The controller firmware (26) interleaves printing operations with non-printing operations during the printing and non-printing phases of the print cycle, respectively. During the printing phase, the controller (26) is dedicated to printing a page or plane. During the non-printing phase, the controller is free to perform other tasks, such as compressing raster data for subsequent printing. The printer is configured with a set of operating parameters that enable the controller firmware to alternate between printing and non-printing tasks (e.g., data compression). Once released from manufacturing, the printer may, in practice, not perform optimally to the specifications. Thus, another aspect of this invention is to tune the operating parameters to achieve optimal performance for a specific printer. This tuning is a self-tuning technique that is performed in post-manufacture real-time, while the printer is in operation.

Title: Processing and storing mass spectrometry data
Inventor: MALEK ROBERT
IPC: H03M7/30
Filed: 2003-09-25
Abstract: A data compression technique is disclosed for Fourier Transform Mass Spectrometry (FTMS). A statistical analysis is applied to the data in the frequency domain since most of this data is a result of randomly distributed electronic noise. A fit of the whole frequency dataset to the distribution is made to determine preliminary moments of the distribution. The data in the tail of that distribution (which is mainly the peak data) is then removed and the remaining data points are re-fitted to the distribution, to identify the moments of distribution of that remaining noise data. A noise threshold for the mass spectrum is then applied using the calculated moments. The data above the threshold is kept. The whole spectrum can be reconstituted by storing the moments of distribution along with the peak data and then regenerating the noise from those moments and adding it to the peak data.

Patent GB-2406890-A (GB)
Title: Plumbing tool
Inventor: RIPPOLONE JOSEPH D
IPC: F16L55/18
Filed: 2003-11-04
Abstract: A plumbing tool 10A includes an elongated hollow shaft 12A, 12A' and a resilient member 16 attached to the shaft adjacent a shaft end. The resilient member 16 extends radially outward and is sized to closely fit within a pipe (24, figs 2A-2E) inner diameter. Once the pipe has been cut, the tool is forced into the pipe end and the resilient member closely fits within the pipe inner diameter to block fluid flow. As the shaft is hollow, fluid flow is diverted through the shaft. The shaft comprises a first section 12A to which the resilient member 16 is attached, and a second section 12A' which is joined at an angle to the first section. The resilient member 16 is preferably an annular disc. A valve (V, fig 2C) may then be passed over the tool to engage the pipe end. As the fluid is being diverted through the tool, the valve is then soldered to the pipe without concern for the heat sink effect of fluid passage through the pipe. Once the valve has been properly soldered to the pipe end, the tool is simply pulled through the valve and removed. Capping of the pipe end with the valve is therefore rapidly achieved with minimal disruption to the users.

Title: Heat sink material
Inventor: ISHIKAWA SHUHEI
IPC: H05K1/02
Filed: 2002-10-25
Abstract: A heat sink suitable for IC chips, having high mechanical strength, is produced by infiltrating metal into pores in a carbon material, giving increased wettability between the heat sink material and plated solder layer covering the surface.
